ArmPkg/ArmPkg.dec: Redefined PcdSystemMemory(Base|Size) as UINT64
The System Memory region might be out of the 32-bit memory space.
This change has been validated on the FVP AArch64 model using 4GB
of DRAM at 0x8_0000_0000:
- # System Memory (2GB)
- gArmTokenSpaceGuid.PcdSystemMemoryBase|0x80000000
- gArmTokenSpaceGuid.PcdSystemMemorySize|0x80000000
+ # System Memory (4GB)
+ gArmTokenSpaceGuid.PcdSystemMemoryBase|0x800000000
+ gArmTokenSpaceGuid.PcdSystemMemorySize|0x100000000
EFI Shell and Linux kernel boot successfully.
Note: This change has not been validated on AArch32. I expect some
early assembly code to not work.
